NZ Bathymetric Surface Model Index

  • Added 09 Jul 2018
  • Updated 26 Mar 2019

This index enables you to identify freely available digital bathymetric surface models owned by LINZ. This data provides a 3-dimensional model of the surface of the seafloor.

These surface models have been created by LINZ from publically funded single- or multi-beam data collected in the New Zealand coastal area since early 1998. The polygons in the index show the extent of these gridded data models, and include descriptive information, such as the age and quality of the data.

The gridded surface models are not downloadable from the LINZ Data Service, but can be provided to you on request.

Please refer to the LINZ Bathymetric Index Data Dictionary for further information about the attributes of this dataset, and formats in which the data is available.

How to order the data:
Requests for the models should be sent to with “Hydro Bathy Data” in the subject line. Requests must, as a minimum, specify the id and surf_name of the models of interest and the data format (see the options in Section 1.4 of the Bathymetric Data Dictionary).

LINZ has also created 3-dimensional bathymetric surface models for the New Zealand coastal area from data provided by third parties, which is subject to different licencing terms and conditions. View our "NZ Bathymetric Surface Model Index – Third Party" dataset to request this data.
